CIA Triad (Confidentiality, Integrity, Availability)

The CIA Triad is the foundation of cybersecurity. Every security control, policy, or mechanism must align with one or more of these principles.

1️⃣ Confidentiality – Protecting data from unauthorized access.
Example: Encrypting emails using PGP to prevent eavesdropping.
Controls: Encryption (AES, RSA), Access Control (RBAC), MFA, VPNs.

2️⃣ Integrity – Ensuring data remains accurate and unaltered.
Example: A hashing algorithm (SHA-256) ensures a file wasn't modified.
Controls: Digital Signatures, Hashing, Checksums, Data Validation.

3️⃣ Availability – Ensuring data is accessible when needed.
Example: Redundant servers ensure a website stays online even if one server crashes.
Controls: Load Balancers, RAID, Cloud Backups, DDoS Mitigation.
